Wearable anti-falling environmental danger identification alarm device

The invention discloses a wearable anti-falling environmental danger identification alarm device, which comprises a shell, an intelligent element, and a fixing device and an intelligent anti-falling system arranged in the shell. The intelligent element is arranged in the shell. According to the device, a threaded ring can move by sliding a moving block, in the moving process of the threaded ring, a rotating lead screw can rotate, then a first gear can rotate, a second gear can rotate through rotation of the first gear, then a threaded rod can rotate, and a threaded pipe slides upwards under rotation of the threaded ring, and thus,the threaded pipe releases the limiting effect on the lock block; when the locking block is clamped into the side wall of the shell again and the moving block slides reversely, the threaded pipe moves downwards again, the locking block is locked again, the old can conveniently, rapidly and simply wear and take down the device while stable locking is achieved, inconvenience caused to
